These motors are hermetically sealed, encapsulated and water lubricated type with removable cable lead out. The stator windings are of enameled copper wire and the wound stator is mounted in a stainless steel shell and is completely protected by a stainless steel cylinder and stator room is pre-filled with resin. The resin filled in the space between the stator & the stainless steel cylinder dissipates heat quickly resulting in longer motor life. Except stator, other portions of the motor is pre-filled with deionised water containing propylene glycol (anti-freeze agent) which serves as coolant & lubricant for rotor, bushes and thrust bearing. If any leakage of water is observed bring to the notice of the distributor. Dynamically balanced rotors of these motors maintain uniform clearance thereby giving better efficiency and increase the life cycle of the water lubricated bush bearings. Specially designed high performance thrust  bearings are used that can withstand high axial thrust loads and upthrust loads with minimum wear and tear. The unique design of thrust bearings creates a wedge of water between the shoe and the disc and there by it gives better water lubrication and increased the life cycle of the thrust bearings. Pressure equalizing rubber diaphragm is provided to guard the pressure and volume variations of the water inside the motor. Motor sealing are made by means of 'O' rings, shaft seals and sand guard to avoid ingress of well water, sand and fiber particles into the motor. Care should be taken to ensure that the motor does not run when it is not submerged in the water. To prevent the motor dry running, install water level monitor / dry run preventor. The motor needs a constant flow of water past it's body to keep it at correct operating temperature. Ideally, the motor should be set just below the level at which water the bore well when this level is not ascertained fit a "flow inducer pipe" over the pumpset to ensure adequate cooling. It is mandatory to install C.R.I. Control box for all single phase 3 wire motors. All 3 Ph motors require an adequate motor protection control panel.
